Beer Neutralizer Question

I got a bottle just to check it out and had a question about the expiration date. Do all the bottles of this have a very short life span/early expiration date? Like I said I received mine the other day and the expiration/best if used by date is December 2007 and was just curious (Just because it so short compared to other supps.)

I don't really plan on needing to use the entire bottle by then and was hoping to just use this one on the rare occasions I would need it and was curious to see if I received maybe an older bottle or like I said before there all shorter life span bottles?
